Well hello everyone!! I am new here and completely new to gardening!!

I have built a 4x6 raised bed that is 10-inches deep, that will be in full sun for at least 8 hours a day. Now I am looking to fill it and get my plants in there.

I have been doing a lot of online research regarding what type of soil I need to use and and how much of each. I am looking for a little guidance and to know if I bought the right stuff.

My native soil is garbage...so I am filling the bed with other stuff.

I bought 14 cu. ft. of Miracle Grow Garden Soil, 3 cu. ft. of Peat Moss, and 3 cu. ft. of a Manure/Hummus mix. Is this good??

Also, when I go to mix the soil....do I mix everything together and then fill the bed?? Do I put some down in layers and just mix the top??

Any and all help is greatly appreciated!! Thanks in advance!!
